Title: Process and apparatus for the treatment of peat
IPC: E21C49/00
Filed: 1951-03-07
Abstract: 711,044. Preparing peat. HESEPER TORFWERK GES. March 7, 1951 [Sept. 7, 1950], No. 5529/51. Class 50. [Also in Group XXX] In a process for air-drying peat, peat sods which have been cut and deposited in rows on a drying field, the sods from at least two rows being in part turned over and relaid on the ground and in part turned over and deposited on top of those relaid on the ground, the heap so formed being after a time relifted and rearranged and finally transported into a large heap together with the sods from other similar rows. Apparatus for carrying out the process comprises a machine mounted on movable tracks and having at one end a sectioned pick-up drum 4, one section 4b of which turns over the sods it picks up and in co-operation with a roller 6 relays them on the ground between guide plates 9, while the other sections 4a and 4c transfer their sods to endless belt conveyers 7 and thence to further endless belt or other conveyers 7a which deposit the sods on top of the sods relaid on the ground. Guide plates 8 are arranged on the conveyers 7 to deliver the sods obliquely on to the conveyers 7a and the pick-up drum 4 is provided with spikes or other holding means. At the end of the machine remote from the pick-up drum 4 there is attached a take-up apparatus 11 which may be of the type described in Specification 698,510, [Group XXX], to carry out the rearranging of the heaps of sods thus formed and a conveyer 12 of adjustable length provides for the final collection of the heaps into one large heap.

Title: Slide projectors
IPC: G03B23/04
Filed: 1974-02-07
Abstract: 1458441 Slide projector EASTMAN KODAK CO 7 Feb 1974 [7 Feb 1973] 05616/74 Addition to 1329195 Heading G2J The invention is a modification of the slidechanging mechanism of Specification 1329195, the movement of the sliding member 1 and the slideengaging member 2 being controlled by a camdriven transport lever 13. The slides are removed from the magazine 8 one by one, from the lower end of the stack 9, as described in the earlier Specification. The slider 1 has a nose 1f at one end, which is engaged in a fork-like end 13a of the threearmed lever 13. This is pivoted on a pin 14, and has at its lower end a pin 13e which engages in a cam slot 15a in the cam plate 15. A latch 16 is pivoted on cam 15 by a pin 18, and is urged clockwise by a spring 23 to abut against a cranked end 11a of a release lever 11. A lug 16a of latch 16 extends through a cut-out 15b in the cam plate to a region below the plate where it can engage a ratchet wheel (20), Fig. 4 (not shown). The release lever 11 is drawn clockwise by a spring 22. Fig. 1 shows the initial position. When lever 11 is pivoted anticlockwise by pressing the handle end 11c downwards, its end 11a disengages from latch 16, which is then pivoted clockwise by spring 23. The lug 16a moves into engagement with the ratchet wheel (20), which is continuously driven by a motor-driven gear (21). Thus the whole cam plate 15 is now driven clockwise, so that the lever 13, by virtue of its engagement with cam slot 15a, pivots anticlockwise, and the slide change operates as in Specification 1329195. At the same time the projector shutter 6 is actuated by a further arm 13b of lever 13. After one complete revolution of cam plate 15 the Fig. I position is reached again. The latch 16 once more engages the end of lever 11, and is so pivoted out of engagement with the ratchet wheel (20), so that movement of cam plate 15 ceases. If lever 11 is constantly held in the release position, the slide-changing operation repeats continuously. Lever 11 can be actuated by remote control, by energising an electromagnet 19.

Title: Improvements in refractory bricks
IPC: C04B35/03
Filed: 1936-03-06
Abstract: In a process for the production of basic refractory bricks, dolomite or magnesian limestone is calcined, some of the lime is removed, and an acidic flux is introduced by treatment with an aqueous solution of a metal salt capable of reacting with the magnesium and calcium hydroxides to produce an insoluble metal oxide or hydroxide.  The lime may be removed by treatment with water in the presence of air or carbon dioxide, or by treatment with hydrochloric acid or an aqueous solution of a salt capable of forming a soluble salt with calcium, e.g. magnesium chloride, barium chloride, Carnallite or Bischopite. The flux may be introduced before, during or after the removal of the lime. Suitable salts for the introduction of the flux are chlorides of iron, aluminium, chromium or manganese.  Ferrous chloride is preferred.  The material after removal of the lime and incorporation of the flux is thoroughly mixed and burnt to a clinker.  This is crushed, mixed with an oil binder containing phenol or cresol, moulded to shape and burnt.  In an example, 1000 lb. of dolomite is burnt at 900-950 DEG  C., slaked with water and treated by immersion in about 500 gallons of water into which is run a solution of ferrous chloride prepared by dissolving 31 lb. of scrap iron in hydrochloric acid and a solution of magnesium chloride prepared by dissolving 147 lb. of magnesitc in hydrochloric acid.  The slurry is washed by decantation, dried and burnt to a clinker.  The clinker is crushed to a grog and dust and moulded into bricks.  The bricks are immersed for three hours in an oil solution of phenol or cresol and drained.  The burnt dolomite before treatment contained 65 per cent of lime and approximately 20 per cent of this was removed by the treatment.
